VISE.

SIPECIFIGATION forming part of Letters Eatent No. 747,033, dated December 15, 1903.

Application filed March 12, 1903- Serial No. 147,488. (No modelfi To all whom it may concern.-

Be it known that I, GUSTAV ADOLF BAU- MANN, a citizen of the United States, residing at Fort Myers, in the county of Lee and State of Florida, have invented new and useful Improvements in Vises, of which the following is a specification.

This invention relates to work holding Vises; and one of the objects thereof is to provide and construct a vise which will automatically clamp the work between the jaws thereof.

Another 'object is to dispense with the ordinary' screw commonly used for adjusting the two jaws and provide in lieu thereof means for removing the pressure against the movable jaw, so that the work can be removed in such a manner that both hands of the operator will be free to manipulate the work. I

Another objectis to provide means for adjustably controlling the opposing jaws for work of diiferent thicknesses.

Other objects as well as the novel details of construction will be specifically set forth hereinafter, reference being had to the accompanying drawings, in which- Figure lis a perspective view of a vise constructed in accordance with my invention, and Fig. 2 is a vertical longitudinal sectional view through the same.

In constructing the device an approximately rectangular skeleton frame is provided, which consists of the two end pieces 1 and 2, connected at their respective corners by the horizontal parallel supportingbars 3, 4, 5, and 6. The lower longitudinal supporting-bars 3 and 4 are secured at the lower corners and on opposite sides of the vertical end pieces 1 and 2 and are provided in their upper edges with notches or grooves 7, forming a rack and alining with similar notches or grooves 8 in the upper longitudinal bars 5 and 6, which are connected to the upper opposite corners of the respective end pieces 1 and 2. v

9 designates the rigid jaw, which consists of a vertical strip havingits upper extremity curved in the form of a flange 10, disposed at a right angle to the body portion of the jaw 9. This jaw 9 is rigidly fastened between the supporting-bars 3and4and 5 and 6.

The movable or pivoted jaw 11 is secured to the bars 3and 4and adjacent to the lower extremity of the rigid jaw 9 and is provided at its upper terminal With a flange 12, coinciding with the flange 10 of the jaw 9. The jaw 11 is approximately wedge-shapedthat is to say, the outer edge 13 of the jaw 11 is cut at an angle to the inner edge, so that the outer surface diverges toward the upper terminal of thejaw. Astandard 14 is arranged adjacent to the frame and bifurcated at its upper extremity to form arms 15 and 16, between which is journaled an elongated bar 17, which extends transversely of the frame and one end of which projects therethrough between the upper and lower supporting-bars. Between the fulcrum-point of the bar 17 and one extremity is an actuating-block 18, which is secured to the bar and is arranged adjacent to the diverging surface of the moving jaw 11. This block is to be moved vertically, so that the upward movement of the block will force the movable jaw toward the rigid one and a downward movement will release it or permit it to move away therefrom, owing .to the fact that the heavier portion of the jaw is at the upper extremity and to one side of the pivotal point thereof. In order that the block 18 will be moved in a vertical direction, I provide an adjustable weight 19 at the opposite end of the bar 17, which engages one of the teeth of the rack 20, formed on the end thereof. The forward or opposite end of the rod 17 can be depressed by a foot-piece or treadle 21, hinged to ablock or support 22 and connected at its opposite end to the end of the rod 17 by a flexible connection 23. I

The reference-numeral 24 designates a vertically-arranged strip having oppositely-dis posed lugs or projections 25 near its top, which extend from the edges thereof and restin the grooves 8. Similar lugs or projections 26 extend from the strip 24 near its lower end in opposite directions to engage the notches or grooves 7 in the lower supporlingbars 3 and 4. This strip constitutes a wall which is adjustable longitudinally of the frame and through the medium thereof in connection with the moving block. The distance that will intervene between the edges of the opposing flanges 10 and 12 of the jaws 9 and 11 can be governed. When the lugs of the wall 24 rest in the first set of notches, the upward movement of the block 18 will bring the opposing edges of the flanges l0 and 12 together, whereby a small article or piece of fabric can be securely clamped therebetween. As the wall is moved away from the jaws, however, the extreme limit of movement of the block 18 will only be effective in moving the ends of the jaws toward each other, but not in contact. This will be desirable when it is necessary to clamp articles of various thicknesses between the jaws.

Of course it will be understood that the standard 14, the bar 17, the block 20, and their appurtenances can be moved toward either end of the frame to coincide with the position of the wall or strip 24. A suitable guide for this purpose can be arranged, if desired. Other changes can be made without essentially affecting the operation of the deviceas, for instance, providing antifrictional rollers or balls in the head 18, whereby an easy movement on the block will take place between the wall 24 and the jaw 11.

This vise or work-holder can readily be set up, and owing to the peculiar arrangement of parts and the wide range of adjustment its adaptability to a multiplicity of uses will be readily appreciated.

I do not limit myself to the specific details of construction shown or the exact arrangement of parts, but I reserve the right to make such changes and alterations as would suggest themselves from time, to time without departing from the spirit of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination with a rigid jaw and a movable jaw pivoted adjacent to the rigid jaw, of a vertically-moving block for forcing the pivoted jaw toward the rigid jaw, and an adjustable wall against which the block slides 5 to operate the pivoted jaw.

pivoted jaw, of an adjustable wall alining with the pivoted jaw, a fulcrumed bar interposed between the wall and the moving jaw, and means on the bar for moving the pivoted jaw toward-the rigid jaw when the bar is actuated.

3. In a device of the character described, the combination with a rigid jaw and a movable jaw, horizontal su pporting-bars provided with grooves, a wall,.means carried by the wall for engagement with the grooves, whereby the Wall will be held in a vertical plane and in adjustablerelation with the movable jaw, and means interposed between the wall and the movable jaw for actuating said jaw.

4. The combination with a rigid jaw and a pivoted jaw, one edge of the moving jaw being arranged to diverge toward its free extremity, a guide-wall vertically disposed, and a block interposed between the guide-wall and the diverging edge of the movable jaw for the purpose set forth.

5. The combination with a rigid jaw and a moving jaw, of an adjustable vertical guidewall arranged in alinement with the rigid jaw and approximately parallel therewith, an actuated lever and its support, said lever extending between the wall and the movingjaw, the support and lever being adjustable with relation to the movingjaw, and an actuatingblock carried by the lever to operate the moving jaw.

6. The combination with a rigid jaw and a moving jaw, the moving jaw having one edge diverging from the other, of a vertical guidewall alining with the rigid jaw and means interposed between the moving jaw and wall and adapted to slide therebetween whereby the movingjaw will be forced toward the rigid aw.

In testimony whereof I afifix my signature in presence of two witnesses.
